What is the difference between a Pareto chart and a histogram?

A Pareto chart is a special type of bar chart that displays defect categories in descending order of frequency with a cumulative percentage line, based on the Pareto principle that roughly 80 percent of problems come from 20 percent of causes. It helps teams focus on the vital few causes that produce the most defects. A histogram is a bar chart showing the frequency distribution of a variable, such as how many measurements fall within specific ranges, revealing patterns like normal distribution or skewness.
